I guess you're looking for the Hubble Constant, which is about - 70 km/s / Megaparsec

I would say it is in a constant state of change and the expansion rates are different in different areas. The universe isn't expanding but is stretching. The universe is already complete like an elastic band in a relaxed state but is being stretched by mass. It is this stretching that gives the illusion of expansion.

Contrary to the observed red shift the expansion is likely slowing down.
The universe is finite so it can"t expand continually.
The expansion is reducing the pressure of space and it may have started to evaporate many years ago.
Just after the big bang space was at it"s most dense. Matter reduced it"s density and celestial events annihilate matter.

Depends on the distance, according to Hubble's law; use the age of the universe as 13.6 billion light years to figure the relation.
